Thank you for pointing out the forum posts. However, I will need to translate them first in order to understand the discussion.
Nevertheless, the question remains as to why ref:NL:bgt is not being used. Are the ref:bgt to be renamed over time?

@streckenkundler> Sorry die Wahl von ref:lfu (oder auch ref:LfU) ist für die Auswertung eher eine schlechte Wahl, weil vermutlich jedes Bundesland ein LfU hat (Langtext des Kürzel siehe oben). Zumindestens sind mir BB und BY schon untergekommen, die brauchen sich nicht zwingend auf gemeinsame Nummerierung einigen. Aber kannst Du mir bitte mal den Link zum Forumartikel schicken? Ansonsten könnte man die Diskussion auch unter
osm.wiki/DE:Schutzgebiete_des_Natur-_und_Landschaftsschutzes führen.

Ich liebe es bei Naturschutzgebiete aufzuräumen ( :) ). Und Du hast recht, zweimal der gleiche Wert geht nicht.

Aber ich habe mal nach geforscht: lfu könnte für das Landesamt für Umwelt stehen (es gibt neben ref:lfu auch eine Schreibweise ref:LfU).
Dann habe ich aber den Wert nach gesucht und bin auf https://data-naturerbe.nabu.de/schutzgebietssteckbriefe/Wumm-See_und_Twern-See.pdf gestoßen. Danach ist dies aus dem Umfeld Natura2000. Das bestätigt sich auch das BB-LfU mit dem Datenblatt https://lfu.brandenburg.de/daten/n/natura2000/sdb/ffh/2842_301.pdf.

Übrigens Aufräumen müsste man auch bei dem Them natura2000 (siehe https://taginfo.osm.org/search?q=natura2000)

Hello! Please have a look on relation/222096/. What is the mean of the very long key? Is this a copy and paste error? Did you mean the key colour?

From the comment, I gather you mean building=yes?

Hello! Quick question. The references for nature reserves also mention the federal state. See https://taginfo.osm.org/search?q=NSG. Is there a reason why you are not including this information?

Hallo! Kurze Nachfrage. Bei den Referenzen der Naturschutzgebieten wird auch das Bundesland genannt. Siehe https://taginfo.osm.org/search?q=NSG. Gibt es einen Grund, dass Du darauf verzichtest?

Hello! Short question: What is the difference between the keys ref:FR:CD63 and (the new) ref:FR:CD74? See alsohttps://taginfo.osm.org/search?q=FR%3ACD.
Thank you for your explanation.

Bonjour ! Petite question : quelle est la différence entre les codes ref:FR:CD63 et (le nouveau) ref:FR:CD74 ? Voir également https://taginfo.osm.org/search?q=FR%3ACD .
Merci d'avance pour votre explication.

Hello! Is there a reason why you are using the key ref:NL:BGT (see https://taginfo.osm.org/search?q=BGT) instead of ref:bgt? If the NL is to be included, then ref:NL:bgt would be the more appropriate notation.

Hallo! Is er een reden waarom je in plaats van ref:bgt de sleutel ref:NL:BGT (zie https://taginfo.osm.org/search?q=BGT) gebruikt? Als de NL erbij hoort, zou ref:NL:bgt toch de meer aangepaste schrijfwijze zijn.

I don't understand your reference to the wiki. The Wikidata value points to a park called Green Park. So the name of the park has been changed.

reduce advertising from description: changeset/172943967

hello! Please be careful! You moved the node node/4941456378 (a street crossing) more than 100 meters over streets and buildings.
I moved the node back to the original position.

I agree with you (but it wasn't clear without further information). I have changed the key elements as follows:
note="\"sign saying our office is closed to the public\“”
name=Solstice
office=property_management
opening_hours:visitors=24/7 off
Feel free to change it.

remove description under changeset/172928904.

There is no entry in the wiki about this, and the forum is not required reading.
The argument is not a very sound justification for a mechanical edit. Please note that we already have many sources of error with the topic name:<operator> regarding name:<language>. I also find the accusation that I am starting an edit war because I consider the first (!) entry to be an error to be rather rude and not conducive to discussion.

Welcome to OSM! I reverted you entry, because your business isn't part of te street.

Unfortunately, I had to revert your first attempt at ALPR monitoring because the entry didn't make sense. I found an example that might serve as a good template: node/13160901909.

Welcome to OSM! I reverted your change set, because there is no address and business description.
